Public, routable address (assignable to a host on the internet).
This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
The digit sequence 31523789 first appears in π at position 549,973 of the decimal expansion (the 549,973ordinal-suffix:rd digit after the integer 3).
